1. It is well known that the quick development of electron­ics began with the invention of transistors. They replaced elec­tronic tubes due to their numerous advantages. One of the main advantages of the transistors in comparison with the vacuum tube is absence of filament power loss. One of the principal caus-

es of damages in electronic circuitry is high temperature. Theheat causes breakdown of tubes and other circuit elements that are very sensitive to this influence. The transistor, on the other hand, does not heat its surroundings.

Another advantage of the transistor is its long life. The life of the average transistor is more than ten thousand operating hours. Because of its long lifetime and raggedness, the transis­tor is very reliable and has much better efficiency in professional equipment.

2. As we know, transistors replaced electronic tubes due to their numerous advantages. One of the advantages of the tran­sistor is its small dimensions. Because of their small size, the absence of heating and other properties, transistors make it pos­sible to produce compact, small-dimensioned electronic devices which consume very little power.

In conclusion it is important to note that transistors revolu­tionized many fields of technology. They are successfully used for direct transformation of heat energy by means of thermal elements. They are also used to convert radiant energy into elec­tricity with the help of photocells or solar batteries. Light sources and lasers are built on the basis of transistors. They find wide application in computers, automatic devices, aviation, commu­nication, etc.

Text У. THE FIRST CALCULATING DEVICES

Let us take a look at the history of computers that we know today. The very first calculating device used was the ten fingers of a man's hands. This, in fact, is why today we still count in tens and multiples of tens.

Then the abacus was invented. People went on using some form of abacus well into the 16^th century, and it is still being used in some parts of the world because it can be understood with­out knowing how to read.

During the 17^th and I8^lh centuries many people tried to find easy ways of calculating. J.Napier, a Scotsman, invented a me­chanical way of multiplying and dividing, which is now the modern slide rale works. Henry Briggs used Napier's ideas to • produce logarithm tables which all mathematicians use today.

Calculus, another branch of mathematics, was independently invented by both Sir Isaak Newton, an Englishman, and Leib­nitz, a German mathematician. The first real calculating ma­chine appeared in 1820 as the result of several people's experi­ments.

In 1830 Charles Babbage, a gifted English mathematician, proposed to build a general-purpose problem-solving machine that he called "the analytical engine". This machine, which Babbage showed at the Paris Exhibition in 1855, was an attempt to cut out the human being altogether, except for providing the machine with the necessary facts about the problem to be solved. He never finished this work, but many of his ideas were the ba­sis for building today's computers.

By the early part of the twentieth century electromechani­cal machines had been developed and were used for business data processing. Dr. Herman Hollerith, a young statistician from the US Census Bureau successfully tabulated the 1890 census. Hollerith invented a means of coding the data by punching holes into cards. He built one machine to punch the holes and others — to tabulate the collected data. Later Hollerith left the Census

Until the middle of the twentieth century machines designed to manipulate punched card data were widely used for business data processing. These early electromechanical data processors were called unit record machines because each punched card contained a unit of data.

In the mid—1940s electronic computers were developed to perform calculations for military and scientific purposes. By the end of the 1960s commercial models of these computers were widely used for both scientific computation and business data processing. Initially these computers accepted their input data from punched cards. By the late 1970s punched cards had been almost universally replaced by keyboard terminals. Since that . time advances in science have led to the proliferation of com­puters throughout our society, and the past is but the prologue that gives us a glimpse of the nature.
